Chinas economic czar, Vice Premier Liu He, will travel to the United States later this month for the second round of negotiations aimed at resolving the ongoing trade war between the global economic giants.

Commerce Ministry spokesman Gao Feng told reporters in Beijing Thursday that Liu will visit Washington on January 30-31. He was invited by U.S. Treasury Secretary Steven Mnuchin and Trade Representative Robert Lighthizer.

U.S. negotiators were optimistic after the first round of talks in Beijing last week that the two sides would be able to resolve tariff disputes that have upset global markets.

The trade talks are the result of an agreement last month between President Trump and Chinese President Xi Jinping to stop the tit-for-tat tariff conflict between the two countries for 90 days starting on New Year's Day.

The United States has long complained about access to the vast Chinese market and Beijing's demands U.S. companies reveal their technology advances.

If no deal is reached by March 2, U.S. tariffs on $200 billion Chinese goods will rise from 10 percent to 25 percent.
